Vitabiotics Ultra Vitamin D 4000 IU is formulated to support people who need a strong vitamin D3 supplement. D3 (cholecalciferol) is the preferred form of Vitamin D because it’s the same form the skin produces under sunlight. Each tablet is intended for one-tablet daily use. Key roles of this supplement include supporting the immune system, maintaining healthy bones and teeth by helping with absorption of calcium and phosphorus, supporting normal muscle function, and aiding cell division. The product is often marketed under “Maximum Strength” in Vitabiotics’ Ultra range, meaning it is higher than their “Extra Strength” and “Super Strength” variants. The pack size is typically 96 tablets. The product is usually made in the UK.
